Comparing Quantitative and Qualitative Methods for Detecting the In Vitro Activity of Colistin against Different Gram-Negative Bacilli
( Austin Publishing Group , 2021 , Article)The surge in the prevalence of Multidrug-Resistant (MDR) Gram-negative bacterial infections with limited treatment led to colistin reusing to treat MDR infections. This study aimed to determine economical, simple, and ... -
Comparing the Metabolic Profiles Associated with Fitness Status between Insulin-Sensitive and Insulin-Resistant Non-Obese Individuals
( MDPI , 2022 , Article)(1) Background: Young non-obese insulin-resistant (IR) individuals could be at risk of developing metabolic diseases including type 2 diabetes mellitus. The protective effect of physical activity in this apparently healthy ... -
Comparison between Thermo-Alkaline and Electro-Fenton Disintegration Effect on Waste Activated Sludge Anaerobic Digestion
( Hindawi Limited , 2019 , Article)Disintegration of municipal waste activated sludge (WAS) using thermo-alkaline (TA) and electro-Fenton (EF) methods was investigated and compared in terms of the efficiency of sludge solubilisation and enhancement of ... -
Comparison of antibody immune responses between BNT162b2 and mRNA-1273 SARS-CoV-2 vaccines in naïve and previously infected individuals.
( Oxford University Press , 2021 , Article)Two mRNA vaccines, Pfizer-BNT162b2 and Moderna-mRNA-1273, obtained the Emergency Use Listing by WHO for preventing COVID-19. However, little is known about the difference in antibody responses induced by these two mRNA ... -
Comparison of Available Methods for Investigating The in vitro Activity of Colistin Against Different Gram-Negative Bacilli
( Qatar University Press , 2021 , Poster)Background: The surge in the prevalence of multidrug-resistant (MDR) Gram-negative bacterial infections with limited treatment options and the decrease in the development of new antibiotics are challenges that lead to the ... -
A comparison of bio-crude oil production from five marine microalgae – Using life cycle analysis
( Elsevier , 2022 , Article)Marine microalgae biomass could offer a viable feedstock for sustainably producing biofuel by hydrothermal liquefaction. In this study, five promising marine microalgae (i.e., Tetraselmis, Picochlorum, Synechococcus, ... -
Comparison of biocrude oil production from self-settling and non-settling microalgae biomass produced in the Qatari desert environment
( Center for Environmental and Energy Research and Studies , 2019 , Article)The present study investigated the growth, harvesting, biocrude conversion, and recycling of the HTL aqueous phase for one self-settling (i.e., Chlorocystis sp.) and another non-settling (i.e., Picochlorum sp.) marine ... -
Comparison of BPN, RBFN and wavelet neural network in induction motor modelling for speed estimation
( Taylor and Francis Ltd. , 2020 , Article)This paper discusses the question of estimating a neural network induction motor speed. The neural network is trained in the relationship between stator currents and rotor speed. Rotor currents and speed are created using ... -
